Theshalt i) extends laterally at both ends beyond the 7 main fro-inc and carries the wheels E whichlatter are provided with the pulleys E to receive belts.

forming & trough-like structure extendin the full length of the buckets which Will operate to receive. the force of the current in order that the wheels may be operated with the full strength of the current in the opera;- tion 01" the invention.

The elevator ironic comprises two side frames F hitVJIlQ the longitudinal bsrs F provided with a central beein F box F" forming a bearing for the pivot shaft G which is mounted in the bearings c of the main frame. This shaft G forms the main support for the elevator frame, the side frames of which are connected by the crossl srs f, see Fig. 2, and the side frames are provided at their lower ends with beams 21 supporting the boxes F for the lower shaft of the elevator and at their upper ends with the bridge or saddle beams il having the box F "for the upper shaft or the elevator, is will be understood from Figs. 1, 2 and The beams i are adjustable .vithin the side frames b fitting; the ends thereof in 1I1OI' shaft 5 trams and also in the bomcsa oi the main having a...

frame and provided with a pulley H connected by belt H with the corresponding.

pulley E of the drive shaft. The elevator frame also has an upper shaft I journaled in the boxes F and provided with a pulley I i are hinged together at K at their meeting ends forming an endless chain and the buckets are constructed, as best shown in Figs. 1, 3 and 6 with the-lower side plates K the top plates K and the front plates K the latter inclining upwardly from the outer ends of the lower side plates nearly to the outer ends of the top plates leaving an opening K through which the water discharges after the buckets have reached their uppermost position and start to descend; This construction is important as the buckets will fill readily in passing through the water, will hold the water securely as they ascend, and will rapidly discharge the water, the top plates K being inclined to facilitate the dischar e of the water from the buckets as the buckets start to descend. Any suitable form of receptacle may be arranged to receive the water from the buckets as they discharge at the upper end of their descending movement.

It will be noticed that my invention involves no complicated gearing likely to get out of order, the different parts which are connected being united by a direct connection and. so constructed as to prevent them from getting outof order .in the ordinary use of the invention.

In operation when the apparatus is located and suitably anchored in a stream of flowing Water the Water will turn. the .drive wheels which by the belt gearing described will operate to turn the elevator, the water acting with force upon the concave paddle blades and the connections from the drive shaft to the upper and lower ends of the elevator will operate to equalize the strain on the apparatus and thusv increase the power and improve the running of the apparatus in the use thereof.

It will be noticed that the elevator shaft at the base thereof moves in two sets of boxes, one on. the elevator frame and one on the main frame so that the elevator frame is securely connected at its lower end with the main frame and is steadied by sucb connection, and the intermediate bearing presently described, position so that the lower pulley of the elevator will be maintained in proper position to be driven by the belt H in the operation of the invention as before described.

Between its ends the elevator shaft is provided with boxes F in which the shaft G is' held, the said shaft being also held. in the boxes a of the main frame. These boxes a being carried on the bridge beams a and the latter being adjustable vertically by means of the keys at", as before described, the elevator frame may be raised or lowered by the proper operation of the keys of to rest or case the lower shaft H in its bearings so that the weightof the elevator frame and the entire load thereof may be transferred. to the dead or intermediate shaft. G thus doing away with the friction which might arise in the boxes carrying the shaftsH and I for moving the endless elevator in the use of the invention, thus reducing the ower required for the operation of the on less elevator to a'minimum. T he upper shaft 1 is also mounted in adjustable bearings has its boxes resting'on the bridge or saddle beams i andmay be adjusted by the proper manipulation. of the keys i to raise or lower the shaft whereby to compensate for contraction and expansion in the use of the invention. be noticed that the elevator frame has an upper shaft and a lower shaft which operate to drive the endless elevator and is also provided with an intermediate shaft, the latter having bearings in the main frame and means being provided in the main frame whereby the said bearings may be raised and lowered for the purpose described.

In Fig. 12 I show a somewhat difi'erent construction in which the driving wheels are located within the main frame or casing and the sides and bottom of the latter are closed and inclined outwardly on each side at the front of the apparatus so the whole stream or river can be turned into the casing to operate on the driving wheels, thusacting direct and increasing the speed and force of the current and in this construction I may employ two sets of elevator buckets with the elevator frames at the opposite sides of the main frame, as best shown in said figure:

What I claim is' 1. A water elevator substantially as herein described comprising. a main frame, a drive shaft, hearings in the main frame for said drive shaft,'means for raising and lowering said. bearings, water wheels on the drive shaft, pulleys on the drive shaft at the opposite sides of the main frame, an .elevator frame having upper and lower shafts .providcd with pulleys and with wheels for an endless elevator, belts connecting the pulleys of the upper and lower shafts of the elevator frame with the pulleys ofv the drive shaft, hearings in the main- -frame for the lower shaft of the elevator frame, an inter- It will thus the wheels of the upper and lower shafts of below said beams whereby theymay be adelevator frame therein, upper .and lower means for adjusting said bearings up and trough shaped buckets, substantially as set forth.
